IPC: B29C45/50
Filed: 1955-07-01
Abstract: 791,557. Injection-moulding machines. WINDSOR, Ltd., R. H. June 22,1956 [July 1, 1955], No. 19069/55. Class 87(2). The conveyer screw 8 which rotates and reciprocates axially within the cylinder 4, 5, has an enlarged cylindrical piston head 8a the outer diameter of which is equal or substantially equal to the diameter of the screw threads. On the interior of the cylinder are slots 5b, Figs. 1 and 2, or an annular recess 5c, Fig. 3, the slots or recess being so located that when the screw is in its rearmost position, as shown, plasticised material that is being pushed forward by the rotating screw threads passes through the slots or recess into the forward chamber 10 of the cylinder. When the chamber 10 has been filled the screw advances to the left and the piston head 8a pushes material out of the chamber into the mould. A nozzle valve 12 is automatically opened and closed by means including a lever and link mechanism 13 and a hydraulic cylinder 14. A device 11 measures the pressure of the material in chamber 10. Specification 760,480 is referred to.

Abstract: 1,176,415. Transmission line arrangements. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 22 April, 1968 [26 April, 1967], No. 19275/67. Addition to 1,123,582. Heading H2H. [Also in Division G3] The voltage stabilizing arrangement described in Specification 1,123,582, is provided with auxiliary stabilizing means to suppress instability-producing even or near-even harmonics and/or sub-harmonics. As shown, the basic stabilising arrangement comprises a shunt capacitor C and a set of reactors L1 in series with a capacitor CS, the series combination and the capacitor C being connected in parallel with the load ZL. The auxiliary stabilizing means comprise arrangements of inductors, capacitors and resistors constituting filters tuned to absorb the undesired harmonics. Thus filters such as FP1, FP2, tuned to specific even harmonics and a filter FP3 tuned to cover a frequency in the range between the fundamental and the second harmonic may be connected in shunt with the capacitor C. Filters such as FS1, FS2, for suppressing specific sub-harmonics may be connected across the series capacitor CS. Other suitable filter arrangements are described with reference to Figs. 2 to 7 (not shown).

Title: Improvements in or relating to the manufacture of shoes
Inventor: DAWSON PETER HUGH VERNON
IPC: A43D25/06
Filed: 1963-05-18
Abstract: A leather upper is mulled, preparatory to lasting, by impregnating the leather with an aqueous composition containing a water-soluble proteinous material such as gelatin.  The upper is impregnated with the composition by saturating a porous pad with the composition and placing the upper with the pad against the flesh side between the platens of a pneumatic press.  A tanning agent e.g. an aqueous solution of tannic acid may be applied to the upper after the composition has been applied.  The gelatin reacts with the tanning agents present in the leather and becomes insoluble and when the leather is dried causes stiffening of the upper.  The composition may be applied in the toe and counter regions of the upper.

Title: Digital multiplexing
IPC: H03M7/14
Filed: 1974-05-07
Abstract: 1464928 Digital multiplexing STANDARD TELEPHONES & CABLES Ltd 7 May 1974 20035/74 Heading H4L At the transmitter of a data transmission system, successions of sub-groups of digits are selected from each of a number of isochronous serial binary coded digital data streams to be transmitted (registers 31, 32). Corresponding groups are then transferred collectively in parallel as first binary digit groups to a code translator 34 wherein each group is translated into a second group of parallel ternary digits. Each second group is converted from parallel to serial form (serializers 35, 36) and passed to a transmitting output stage. The reverse procedure takes place at the receiver of the system. Thus the separate serial streams to be transmitted are simultaneously multiplexed and code converted to provide signals better optimized for transmission. The binary data in each of two tributary streams in first subjected to a pulse stuffing procedure to bring the two streams into synchronism with reference to a stuffing frame (Fig. 1, not shown). Each stuffed tributary data stream is then applied to a two line parallel scrambler 30 to produce two scrambled streams which are deserialized in two two bit shift registers 31, 32 each providing outputs on two parallel lines. The lines from each register are respectively connected to the four parallel inputs of a 4B3T binary to ternary code converter 34. This converts four digit parallel binary code to three digit parallel ternary code according to a conversion given in the specification (Fig. 4, not shown), and has six output lines, one each for positive and negative marks of the three time slots of the ternary word. Positive and negative marks are respectively serialized at 35 and 36 and applied to an output stage 37 which drives the ternary output to line. Clock control for the serializers, code translator and stuffing rate is all obtained from a single generator 33. At the receiving end, the converse arrangement to that of Fig. 3 is provided for demultiplexing and code translating, with the inclusion of facilities for recovering a clock from the ternary digit stream (Fig. 5, not shown).
